How One Sleepless Night Can Reduce Depression Symptoms

Scientists conducted experiments to induce sleep deprivation in mice. After a sleepless night, the animals became more aggressive, hyperactive and hypersexual. Researchers measured the activity of dopamine neurons, which are responsible for the brain's response to reward, and found that it was higher in sleep-deprived animals. Doctors warned that long-term sleep deprivation is extremely harmful, so it's better to go to the gym or take a walk. However, the new findings can help in selecting the right antidepressant.
